Sleep — the supplement guide for South Africans
The four ingredients with the strongest evidence for sleep are magnesium glycinate, L-theanine, 5-HTP and ashwagandha (KSM-66). They work through different mechanisms — minerals, GABA, serotonin precursor, cortisol — and stack well together. Below: who benefits from what, doses, and timing.
The evening stack for most SA adults
The most replicated daily evening sleep stack: magnesium glycinate 300 mg + L-theanine 200 mg + ashwagandha KSM-66 300 mg taken 30–60 minutes before bed. Each ingredient is well-tolerated, no interaction with each other, and effects build over 2–4 weeks.
If sleep latency is the problem
Add 5-HTP 100 mg in the evening for shorter time-to-sleep. Do not combine with SSRIs/SNRIs. Cycle off after 12 weeks.
If you wake at 3am
Early-morning wake is classic cortisol-driven. Prioritise ashwagandha KSM-66 600 mg/day for 8 weeks + magnesium glycinate at night. Address evening alcohol and caffeine timing.
Why this stack, not melatonin first
Exogenous melatonin works for shifted circadian rhythms (jet lag, shift work) but most SA insomnia is stress- and mineral-driven. Magnesium/theanine/ashwagandha treat the upstream cause; melatonin can be added if the rhythm itself is off (300 mcg–1 mg, not the over-dosed 3–10 mg most SA shops sell).
Sleep FAQ
What's the single most effective sleep supplement?
Magnesium glycinate at 300 mg elemental in the evening has the broadest evidence base and the lowest interaction profile. Start there.
How long before I see results?
Most users notice within 7–14 days. Full effect of the ashwagandha component takes 6–8 weeks.
Are these safe with sleep meds?
Magnesium and theanine are generally safe alongside common SA prescription sleep medications, but always check with your pharmacist.
Can I take all four together?
Yes — they work on different pathways. Many SA adults do this nightly as the 'evening stack'.
What about CBD?
Mixed evidence in randomised trials, and quality control in SA is highly variable. Start with the evidence-led stack above; consider CBD only if persistent issues.
